Plant maturity

Is it true that when a plant starts creating altenate nodes that it is mature and ready to bud. As opposed to the plant having even nodes.

anyone please

Yes that is one sign of sexual maturity. The plant will continue to veg though until you switch the photoperiod. You should be able to find some preflowers at this point. Be a bit more patient next question, 17 minutes is not alot of time.
